Queensland’s long-running fight over how the GST pie is carved up has entered a new phase, with the Queensland Productivity Commission (QPC) now ordered to conduct its own independent review into the economic impacts of Australia’s GST distribution system.
The move comes after a record hit to the state’s revenue: a reduction of 2.3 billion dollars in 2025–26 alone, and an estimated 5.3 billion dollars over the next three years. For industries like construction that rely on public investment, infrastructure certainty and state service capacity, this is more than a political scrap. It is a structural issue that could influence housing supply, project pipelines and workforce stability.
This article unpacks what the QPC review means, why it matters, and how the outcomes could impact Queensland’s builders and the broader construction ecosystem.
Why the GST Review Matters Now
GST redistribution is one of the most significant financial levers shaping state budgets. For a sector like construction, which depends heavily on government spending on infrastructure, training, housing programs and planning system capacity, any change to state revenue can have far-reaching ripple effects.
The timing is also critical. Queensland is heading into a decade of major population growth and record infrastructure demands, particularly in the lead-up to the 2032 Olympic and Paralympic Games. Meanwhile, builders are battling rising input costs, labour shortages and uncertain market conditions.
The concern from the Crisafulli Government is that Queensland’s growth is outpacing its revenue share.
Over the past decade:
- Queensland’s GST revenue grew 28 per cent
- New South Wales grew 58 per cent
- Victoria grew 118 per cent
- Western Australia grew 317 per cent
If Queensland had grown at the national rate, the state would be 6.1 billion dollars better off this year.
For builders, developers and suppliers, these numbers matter because they influence everything from road upgrades and regional infrastructure through to skills funding, approvals resourcing and housing programs.
A Review Aimed at Exposing Structural Flaws
The QPC’s review will examine the economic impacts of the current GST methodology across several fronts:
- The effect on Queensland’s ability to deliver essential services
- How the distribution affects population movement
- Economic outcomes for Queensland relative to other states
- Penalties placed on resource-intensive economies
- The residual impact of policy decisions made during COVID-19
The government argues that the current formula punishes Queensland for growing its resources industry while requiring the state to absorb financial consequences tied to decisions made in other states.
Treasurer David Janetzki has gone as far as saying the system is “seriously flawed”, claiming Canberra’s redistribution away from Queensland comes at a time when the Commonwealth is also retreating from funding responsibilities in areas like aged care and the NDIS, placing further pressure on state budgets.
The Federal Productivity Commission is already conducting a national inquiry, but Queensland officials argue that its terms of reference are too limited to allow for the full, structural review that is needed.
In response, the state has instructed its own Commission to provide an interim report in February and a final report in April.
What This Means for the Construction Industry
1. Capital Works and Infrastructure Planning
When state revenue tightens, infrastructure programs usually feel it first.
The sector has already seen governments in several states delay or re-sequence major capital works due to softened budgets. A prolonged GST shortfall may add pressure to:
- planned road and rail upgrades
- water and utilities projects
- essential infrastructure in growth corridors
- local and regional infrastructure used to unlock new land releases
For developers and builders relying on timely infrastructure to support new communities, any slowdown has flow-on effects to land supply, approval timeframes and sales velocity.
2. Housing Supply and Affordability Programs
With Queensland battling severe rental shortages and growing demand from interstate migration, housing affordability programs remain politically and economically vital.
Reduced GST revenue may limit the state’s capacity to scale:
- social housing initiatives
- build-to-rent incentives
- key worker housing programs
- land activation projects
- planning system reforms
While the state has emphasised its commitment to delivering a “better lifestyle through a stronger economy”, the funding envelope will still determine how much pressure can realistically be taken off the housing system.
3. Workforce, Training and Skills Development
A decade of under-investment in skills was a key talking point of the new government’s early reforms.
Builder sentiment across Queensland continues to highlight difficulties in securing qualified trades, apprentices and site managers. Any GST-driven tightening in training budgets could complicate efforts to stabilise the workforce, especially with large projects ramping up.
The industry’s pipeline for skills; apprenticeships, technical training, and workforce attraction depends on robust state investment.
4. Certainty for Builders and Suppliers
The building sector thrives on predictability. Uncertainty around state revenue can affect:
- forward planning for government-funded projects
- business confidence among commercial contractors
- investment timelines for suppliers and manufacturers
- expectations around approvals and compliance resourcing
Many businesses in the construction supply chain operate on long-term planning cycles. When revenue outlooks fluctuate, it introduces risk into procurement, expansion and hiring decisions.
Why the GST Methodology Is so Contentious
GST distribution is based on horizontal fiscal equalisation, the idea that every Australian, regardless of state, should have access to similar levels of government services.
However, the methodology is complex and heavily influenced by:
- mining royalties
- property market strength
- population growth
- state budget positions
- expenditure patterns
- policy decisions of other states
Queensland’s argument is that it is penalised for being a resource-rich state while also carrying the cost of national economic shocks.
A decade of revenue lag has now reached a point where the state believes the system is no longer fit for purpose.
What to Watch for in the Coming Months
Between now and April, the QPC review is likely to explore several questions that matter directly to the construction sector:
Does the current GST formula adequately account for growth in high-migration states?
Queensland continues to attract interstate movers at record levels. This brings both economic opportunity and service delivery cost pressures.
Is the methodology disincentivising resource development and state-led economic activity?
For a state with major LNG, critical minerals and mining operations, this is central.
How is GST distribution affecting housing supply, approvals and land release timelines?
The pipeline in Queensland’s growth regions depends on planning system capacity, infrastructure and development facilitation.
What structural reforms could help create a fairer, more stable revenue base?
This is the crux of the state’s case.
The Bigger Picture for Industry
For builders, developers, engineers, trades and suppliers, this story is not just about state-versus-federal politics. It is about:
- the stability of future work pipelines
- confidence in the market
- the ability of the state to maintain its infrastructure promises
- investment certainty for new communities
- the resources available to train and retain the workforce
Queensland is on the cusp of some of the most significant building activity it has ever seen. A fair and predictable revenue share is a critical foundation for delivering it.
The QPC review will not solve the problem overnight, but it will provide the evidence base needed to push for national reform, reform that may ultimately influence how quickly Queensland can respond to housing pressures, support its regions, and deliver the projects that builders and communities rely on.
With the interim report due in February and the final recommendations in April, the outcomes will be watched closely across the construction sector.
